Introduction

E-Coder panel was designed to control SDR-devices. It has a wide range of functionality, which makes it a perfect tool for contests.

In the Panel menu, you can see the settings of the E-Coder control panel. In the drop-down Device menu, you can select the type of the connected control panel. In the meantime, only one type is available - E-Coder. Note! If one E-Coder panel is connected to the transceiver, in the Panel menu displayed one E-Coder 1 tab, if several E-Coder panels are connected to the transceiver, in the Panel menu displayed a several tabs E-Coder 1, E-Coder 2 etc. with identical settings for each panel.

In the left part of the menu, you can see the schematic picture of the E-Coder panel with buttons and knobs. Press any button, you'll see the list of the available functions.

The following functions may be assigned to the E-Coder panel buttons:

Unused – button is unused.

Main:

AGC Up/Down – AGC type switching

Band Up/Down – band switching

Filter Up/Down – receiver's filter switching

Mode Up/Down – mode switching

MOX – enable/disable manually operated transmit mode

PA – enable/disable power amplifier

Preamp Up/Down – preamp or attenuator level switching

Power ON/OFF – transceiver's power on/off

RX ANT - enable/disable receive antenna

Step Up/Down – change the tuning step

Tone – enable/disable tone signal in TX mode

WF - enable/disable Wide Filter. Filter for all Nyquist zone. If in the Device menu settings, you set Auto enable checkbox, then you don't need this function on the panel

Zoom In/Out – spectrum zoom modes switching

VFO/RX2:

A>B - assign the frequency from heterodyne VFO A to heterodyne VFO B

B>A - assign the frequency from heterodyne VFO B to heterodyne VFO A

B<>A - frequency exchange between VFO A and VFO B

Change VFO A/VFO B – switching between VFO A and VFO B

IF as RIT – tune the RIT offset by moving the filter over the panorama

LOCK - lock the frequency tuning

RX2 On/Off - enable/disable RX2

RIT On/Off – enable/disable RIT offset

RIT Reset – reset RIT offset to 0

Sub RX On/Off - enable/disable SubRX

Split – enable/disable Split mode

Switch DDS/IF – tuning the frequency by moving the filter over the panorama, in other words changing the digital IF, or when filter stands still and spectrum moves, this is the central frequency tuning

Switch Receiver – switching between software RX1 and RX2. The main knob will tune the frequency of one of the receivers

XIT On/Off – enable/disable XIT offset

XIT Reset - reset XIT offset to 0

While you operate both RX1 and RX2, usually you need to listen to either only one of them or both of them, but in different channels (left / right). To do that we added special functions to the E-Coder panel, which set the mixer for both RXs

Audio:

Listen both RX1, RX2 – default settings, both RXs have equal volume in both channels

Listen RX1 only – listen to the RX1 in both channels

Listen RX2 only - listen to the RX2 in both channels

Listen RX1 in left channel, RX2 in right – listen to the RX1 in the left channel and RX2 in the right channel

Listen RX1 in right channel, RX2 in left - listen to the RX1 in the right channel and RX2 in the left channel

Similar settings were added for VFOs:

Listen both VFO A/B - default settings, both VFOs have equal volume in both channels

Listen VFO A only - listen to the VFO A in both channels

Listen VFO B only - listen to the VFO B in both channels

Listen VFO A in left channel, VFO B in right - listen to the VFO A in the left channel and VFO B in the right channel

Listen VFO A in right channel, VFO B in left - listen to the VFO A in the right channel and VFO B in the left channel

Mute – switch off the sound

Switch RX and mute former – change the software receiver and mute former one
